Air Jacket kettles from Cleasby Manufacturing Co. Inc. boast a bottom-fire design housed in an air chamber that helps safeguard material from scorching and burning. The kettles are specially designed to protect highly sensitive hot-applied rubberized asphalt. They feature an elongated burner tube that extends the length of the material vat to eliminate hot and cold spots and promote uniform heating. Many major material manufacturers also approve and recommended the kettles for heating rubberized asphalt. For more information, call 800-253-2729 or visit www.cleasby.com.
